Abstract

Vacuum-gap Fabry-Perot cavities are indispensable tools for vastly improving the frequency stability of lasers, with applications across a diverse range of scientific and industrial pursuits. However, making these cavity-based laser stabilization systems portable and rugged enough for use outside of controlled laboratory conditions has proven difficult. Here, we present a fiber-coupled laser stabilization system requiring no free-space optics or alignment, based on a 2 mL vacuum-gap Fabry-Perot cavity, with thermal noise-limited performance and 1x10-14 fractional frequency instability. The paradigm of fiberized optical components in compact packages has been instrumental in both advancing the field of optics and leveraging those advances across disciplines to facilitate other fields of study. This portable system represents a major step towards making the frequency stability of cavity-based systems broadly accessible.
